The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles.

Electricity and Magnetism is a standard textbook in electromagnetism originally written by Nobel laureate Edward Mills Purcell in 1963. [1] Along with David Griffiths' Introduction to Electrodynamics, this book is one of the most widely adopted undergraduate textbooks in electromagnetism. [2]
The most common description of the electromagnetic field uses two three-dimensional vector fields called the electric field and the magnetic field.These vector fields each have a value defined at every point of space and time and are thus often regarded as functions of the space and time coordinates.
For example, there were many advances in the field of optics centuries before light was understood to be an electromagnetic wave. However, the theory of electromagnetism , as it is currently understood, grew out of Michael Faraday 's experiments suggesting the existence of an electromagnetic field and James Clerk Maxwell 's use of differential ...
Both exams have the same number of multiple-choice questions and have identical free-response formats. [2] AP Physics 1 has the lowest average exam scores of any AP exam, while AP Physics C: Mechanics has among the highest. [3] Both exams cover a similar mixture of topics, focusing primarily on Newtonian mechanics, kinematics, rotation, and ...
Michael Faraday discovered the converse, that magnetism could induce electric currents, and James Clerk Maxwell put the whole thing together in a unified theory of electromagnetism. Maxwell's equations further indicated that electromagnetic waves existed, and the experiments of Heinrich Hertz confirmed this, making radio possible.
